Hi friends,
In the literature, I have seen the following term: ``non-Galilean invariant''. It appeared in a paper on K-Epsilon turbulence model that uses y in the damping function instead of y+. Please, what means Galilean Invariance? Thanks. |

Galilean Invariance means that the model must not be affected by a Galilean transformation. A Galilean transformation is a change of reference frame from one coordinate system to another moving with a constant velocity relative to the original. Everything in classical physics is Galilean invariant so all good models should also be Galilean invariant in order to be correct.

If, for a wind turbine I use a rotating mesh does this instantly mean that the simulation is not 'Galilean Invariant' ???
